At the airport. The flight is oversold. Guess who got bumped? The lone traveler with carry on luggage. But I got a $200 voucher, so that's something. And I'm not in a rush.

How long do you have to wait for the next flight?

yay for voucher (just in case you have to return)

or can you use it for travel to a new country? does it expire?

Only had to wait a couple hours for the next flight. Now in Dallas and wish I had stevebob's number!

I ca use the voucher towards any United Airlines flight. They fly out of San Luis Potosí, so maybe. I have a year to book the flight and 18 months to use it.
